One of the many pieces of odd but important evidence that supports evolution, and particularly "non-directed" evolution, is the fact that humans are simply not "designed" to stand upright.
The knee is barely able to support us, and, as athletes can attest, is easily damaged and even destroyed.Simple aging wears its components down rapidly. Had we been "meant" to walk on two legs the knee and hip would be much bigger, bulkier, and stronger.
Evolutionary biologists suggest that the first "step" in humans branching off from our ancestor common with the apes was, in fact, standing on two legs. This "freed" our brains and hands to develop as they have.
I'd rather have a big brain and exquisitely fine-tuned hands (not to mention speech!) than strong knees. Wouldn't we all? If you can't "do it all", do what counts. Unfortunately that big brain has convinced us that we can do things with our knees we were never "designed" to do.
There is no free lunch!
